Estenose sintomática da artéria subclávia direita aberrante

The aberrant origin of the right subclavian artery, one of the most common anomalies of the aortic arch, occurs in approximately 0.5% to 1% of the population.

Usually asymptomatic, when symptoms are present they result from compression of the esophagus by the aberrant artery, aneurysmal degeneration or occlusive atherosclerotic disease. Occlusive symptoms are usually treated by surgical revascularization.

The authors present a case of a patient with a history of progressive claudication in the right upper limb, associated with dizziness. The imagiologic study revealed a stenosis of the right subclavian artery. The right subclavian artery had an aberrant course, behind the esophagus and trachea.

He underwent percutaneous treatment with primary stenting of the subclavian stenosis, without complications on the postoperative period. The patient still asymptomatic 4 years after the procedure.

Endovascular treatment has been used with excellent results in the treatment of occlusive disease of the subclavian artery, with few cases described of subclavian artery with aberrant origin.
